Upon Lascoff's arrival in the U.S., he took a position as a chemist and pharmacist with David Hayes & Son from 1892-97 and was in charge of the prescription and tablet department at Merck & Company from 1897 to 1898. Educated in Europe and the United States, Lascoff received his Doctor of Pharmacy degree from the New Jersey College of Pharmacy in 1914, and his Doctor of Science degree in 1938 from Temple University. Lascoff was to become a highly respected pharmacist who labored in the field for over fifty years. In 1899 he opened a drugstore which eventually became known as J. Lascoff & Son Apothecary on Lexington Avenue in New York City. In 1896 Lascoff married Clara Joachismon and they had one son, Frederick Dudley Lascoff who was born in 1900.
The elder Lascoff earned many professional awards, his greatest achievement being the Remington Medal that was awarded in 1937.
